Which term is diagnosed when weight exceeds 20% of standard for height, age, and gender?

• A. Cachexia
• B. Anorexia
• C. Malnutrition
• D. Obesity

Answer: (D)

Excess body weight that goes about 20% above the standard for a person’s height, age, and gender is labeled as obesity. This threshold comes from comparing a person to an ideal or standard weight for their demographic, and tipping past that 20% mark signals an overweight condition with health risks.

Cachexia describes weight loss and muscle wasting due to disease, not simply being above a standard weight. Anorexia refers to a loss of appetite that can lead to weight loss. Malnutrition is a broader term for poor nutrition, which can involve deficiencies or imbalances of nutrients, not just excess weight.
